Misdemeanor
Legal Term

A less serious crime. Under federal law it is one punishable by a year or less in jail.

Motion to Commit
Congress

A motion to send a measure to a committee. In the Senate a motion to commit with instructions is often used to propose changes, for example during debate on a reconciliation bill.

Motion to Concur
Congress

A motion to accept the other chamber's amendment to a bill. Once both chambers agree to the same text, the bill can go to the president.

Motion to Discharge
Congress

A motion to take a measure away from a committee that has not acted on it so the full chamber can consider it. In the Senate it is used under fast-track laws, such as those for disapproving arms sales or agency rules.

Motion to Proceed
Congress

A Senate motion to take up a bill or other measure for debate. It can itself be filibustered, so the Senate often needs a cloture vote just to begin debate.

Motion to Recommit
Congress

A House motion, usually offered by the minority just before the vote on passage, to send a bill back to committee. Since 2021 it cannot carry instructions to amend the bill, so adopting it simply returns the bill to committee.

Motion to Reconsider
Congress

A motion to vote again on a question already decided. It is usually tabled right away, which makes the outcome final.

Motion to Table
Congress

A motion to set aside a pending question without a direct vote on it. It cannot be debated, and agreeing to it usually kills the question.

Motion to Waive
Congress

A Senate motion to set aside a budget rule, such as a budget point of order, so a bill or amendment can go forward. Most waivers take 60 votes.
